NASA revealed the discovery Exoplanet Located in 40 light years from our planetwhich completes its orbit in just 12.8 days and could be habitable.
This exoplanet, called Gliese 12 b, is a “super-Earth.” The size is similar to the size of the Earth Or a little smaller, according to a press release from a pot. Exoplanets are celestial bodies located outside our solar system.
“We have identified the closest Earth-sized temperate world to pass through so far,” commented Masayuki Kuzuhara, an assistant professor at the Tokyo Center for Astrobiology. “Although we have not yet determined whether it has an atmosphere, we consider it to be an exoplanet of Venus, given its size and the energy it receives.” From its star, similar to our planetary neighbor in the solar system.

it is expected that Gliss 12 b It can have two very different types of atmosphere. One would be similar to Earth, consisting of oxygen, nitrogen and other elements that support life. The other might be like Venus, which means extremely high temperatures.
“The early atmosphere of Earth and Venus is thought to have been stripped away and then replenished by degassing of volcanic gases and bombardment of remaining material in the solar system,” explained Larissa Palethorpe, study co-author and student at the University of Edinburgh. University College London.
Exoplanet: This is what is known so far
- Gliese 12 b is an exoplanet located 40 light-years from Earth and completes its orbit in 12.8 days.
- The exoplanet Gliese 12 b is similar in size to Earth or slightly smaller.
- Gliese 12 b orbits a red dwarf star known as Gliese 12, which is about 27% the size of the Sun and has a surface temperature of 60%.
- NASA astronomers estimate that without an atmosphere, Gliese 12 b’s surface temperature would be about 107 degrees Fahrenheit (42 degrees Celsius).
- Gliese 12 b could have an Earth-like atmosphere, hospitable to life, or a Venus-like atmosphere, leading to extremely high temperatures.
Gliss B, between Earth and Venus
“Earth is habitable, but Venus is not due to its complete loss of water. Since Gliese 12 b has a temperature between Earth and Venus, its atmosphere can teach us a lot about the habitability paths that planets take as they evolve,” Palethorpe added.
NASA reports that the planet Gliese 12 b orbits a red dwarf star known as Gliese 12. This star is only 27% the size of the Sun, and its surface temperature is about 60% that of the Sun.

Assuming the planet has no atmosphere, NASA astronomers calculated that the surface temperature of Gliese 12 b is about 107 degrees Fahrenheit (42 degrees Celsius).
